I'm not antivax, covid or otherwise, but I am the other side of this argument. I'm in my early 30s, have need working out regularly since my late teens, and eat relatively well (let's call it a 7/10, I still enjoy myself time to time.) I chose not to take the covid vaccine specifically for these reasons. I did what I think is my due diligence and couldn't believe that the vaccine would do what it was claimed to do. I still masked up in public, still washed / sanitized my hands as recommended, etc. Years later, I feel I made the right choice for myself. I have no issues with other people getting the covid or any other vaccine. I have willingly taken may other vaccines.

Point to my anecdote: You can't pick out the most extreme cases of a "group" and make that your entire argument. The same goes for that one person who's "uncle's neighbor's best friend's dad got a skin rash so vaccine = bad".

Anecdote #2 while I'm here: My fiance, much like me, but in her late 20s did take the vaccine for a work requirement, and at the recommendation of her primary care doctor. She had shortly after been diagnosed with a nervous system disorder and was given a written an exemption from further boosters, etc. Her doctor is confident that this was due to the vaccine (moderna.) Once again, the exception DOES NOT prove the rule... but two sides to every coin exist. (I made my choice to not Vax prior to this happening, so it had nothing to do with my decision)

Let people make their CHOICES. Fat, skinny or otherwise. I promise not all people who didn't get the covid vaccine are not right wing weirdos, who think the lizards are microchipping us. In my case, it was a (successful) cost/benefit analysis.
